Title: Image recorder
Inventor: SUGIURA YOSHINORI
IPC: G03G15/00
Filed: 1989-09-25
Abstract: PURPOSE:To make the entire device compact by providing the image recorder with a first guide member, which changes an advancing direction almost an angle of 180 deg. right after a paper is fed, and a second guide member, which again changes the advancing direction 180 deg. right before the paper is ejected. CONSTITUTION:The supplied transfer paper makes a U-turn by means of a first U-turn/carry guide 8, is nipped by resist rollers 9a and 9b, and stops. During a period of time that the transfer paper is carried while it is nipped by a photosensitive drum 5 and a transfer roller 10, a toner image on the photosensitive drum 5 is transferred on the transfer paper. The transfer paper is led to a pair of fixing rollers 11a and 11b, passes between the carry guides 17 and 18, and is led to a pair of carry rollers 12a and 12b, the direction in which the paper advances is altered by a second U-turn/carry guide 13, and the paper is ejected on the top of a stack 6 of transfer papers by the pair of paper ejecting rollers 14a and 14b and with the aid of an auxiliary carry guide 15. Thus, installation space for the entire device can be minimized, and its height can be also reduced as much as possible.

Title: Image sensor
Inventor: OKAMOTO HIROYUKI
IPC: H01L27/146
Filed: 1989-09-25
Abstract: PURPOSE:To obtain a protective film which does not adversely influence field effect transistor characteristics due to film formation conditions of a silicon nitride film by a method wherein two insulation films are interposed between a scanning circuit and a photoelectric transducer while one of the layers is a silicon oxide film and the other is the silicon nitride film. CONSTITUTION:After an interlayer insulation film 6 is deposited, another interlayer insulation film 13 is formed. These interlayer insulation films 6, 13 are a combination of a silicon oxide film and a silicon nitride film each wherein electron spin concentration of either film is preferably 2X10<17>cm<-3> or more. To form an interlayer insulation film having such concentration, Ar<+> ions are implanted into a silicon oxide film and when a silicon nitride film is formed by plasma CVD method, low pressure CVD method, etc., temperature of a substrate 1 is 400 deg.C, flow ratio of NH3/SiH4 is reduced, and Ar<+> ions are implanted to the formed silicon nitride film. Thus a protective film which does not adversely affect transistor characteristics due to film formation conditions of the silicon nitride film can be obtained.

Filed: 1983-12-26
Abstract: PURPOSE:To ensure the allowance for a position regulating pin even when the tilt of the position regulating pin is decreased by fitting the position regulating pins to plural plate springs different in spring constant in a rotary driver such as a magnetic disc. CONSTITUTION:Each end of the 1st plate spring 25 having a certain constant and of the 2nd plate spring 26 having a spring constant larger than that of the 1st plate spring 25 are fixed to a lower face of a motor hub 16 with a common fastening screw 27. The position regulating pin 19 is fitted to the 1st plate spring 25 and a part of the pin 19 is exposed from the upper face of the motor hub 16 with an elastic force of the plate spring 26 mainly at normal state. Through the constitution above, a force to regulate position is given by the 1st plate spring for the position regulating pin and since the recess required for the position regulating pin is allowed by the 2nd plate spring having alarger spring constant than the 1st plate spring, sufficient recess of the position regulating pin is ensured while the tilt of the position regulating pin is decreased.

Title: Ecl integrated circuit
Inventor: KUMAGAI MUTSUYUKI
IPC: H03K19/086
Filed: 1990-09-18
Abstract: PURPOSE:To allow integrated circuit to be hardly malfunctioned due to noise introduced externally by setting a different logic level depending whether or not a high speed operation is implemented to each latch circuit arranged on a same chip. CONSTITUTION:A logic level of plural latch circuits 111-11N is set in response to a prescribed circuit parameter and the logic level is individually set in response to the required operating speed. That is, since latch circuits 31,32,38 are high in their operating speed in the normal operation, the logic level is set to a smaller level (800mV or below). Moreover, since a latch 33 has only to latch system information in the normal operation and does not required any high speed operation, the logic level of the latch circuit 33 is set to 800mV, then the noise margin is set larger than that of the other latch circuits. Thus, the inversion of latch circuit latching a prescribed data for a long time due to noise is prevented while keeping a prescribed data.

Abstract: PROBLEM TO BE SOLVED: To prevent the deposition rate of a silicon nitride film or a silicon dioxide film from being reduced and to enable forming a thin film of highly even film thickness on a large-area substrate by a method, wherein an optical pumping of gas molecules, which do not generate a deposition of the thin film by a decomposition of the gas molecules themselves, is conducted in a gas-introducing device which is different from a reaction tank and the silicon nitride film or the silicon dioxide film is deposited, without putting directly light in the substrate and the reaction tank. SOLUTION: A GaAs substrate 3 is charged on a sample stage 2 in a reaction chamber 1, the substrate 3 is heated by a heater, a valve 4 is opened, NH3 gas is introduced into a gas cell 6, an AsF excimer laser beam is focused and introduced in the gas cell 6 by a lens 9 via an optical window 8, in such a way as to have the focal point of the laser beam in the cell 6 and the excited HN3 gas is put in the chamber 1 from the cell 6 through an orifice 7. A valve 10 is opened, SiH4 gas is put in the chamber 1 through a nozzle 11, and a deposition of a silicon nitride film is started. As a result, the growth rate of the silicon nitride film is held stably, extending over a long period of time, and the formation of a thin film, which has a high uniformity in film thickness, is made possible.
